Expert Answer:

begin mathsize 18px style straight w squared equals straight l cross times straight h....... left parenthesis 1 right parenthesis
surface space area space equals space
2 open parentheses lh plus lw plus hw close parentheses equals 216
lh plus lw plus hw equals 108....... left parenthesis 2 right parenthesis
lwh equals 250........ left parenthesis 3 right parenthesis
solve space equations space left parenthesis 1 right parenthesis comma space left parenthesis 2 right parenthesis space and space left parenthesis 3 right parenthesis space together space to space get space the space values
